You do not know who you are talking to unless you ask. – Keep it simple: What do you do?
The beautiful thing about asking questions is that most times you will be asked the same question back. Here lies the opportunity to share about the elements of your project that connect to the person with whom you are speaking. By creating this bridge of connection, the most natural thing to do next is exchange information. =)
Next thing you know, you’re connected to hundreds of will seem like completely random individuals until you start leveraging connections and seeing that world is indeed a very small place.
